I think this completely depends on what comes after it.
I cant see how saying something like "I need to be able to trust my partner" is controlling. To me, thats a boundary issue. Im not going to be in another relationship where Im checking on my partner's phone activity or whereabouts. Thats about ME, not about my partner - that person can choose to do whatever they want, but if the choices lead to that kind of attitude, then Im not going to put up with it.
